Patient
male, 59 year(s)
 
 
  • Figure 1
    Axial T1W SE before (a-b) and after (c-d) Gd IV
     

    Note the spontaneously high signal areas in the tumour extending to the central skull base and right cavernous sinus.

     
    Area of Interest: unknown; Imaging Technique: Axial T1W SE before (a-b) and after (c-d) Gd IV;

    Note the invasion of the right orbit, as of the whole ethmoid

     
    Area of Interest: unknown; Imaging Technique: Axial T1W SE before (a-b) and after (c-d) Gd IV;

    Contrast enhancement after Gd is heterogeneous, with areas of necrosis

     
    Area of Interest: unknown; Imaging Technique: Axial T1W SE before (a-b) and after (c-d) Gd IV;

    Same as 1b, after Gd

     
    Area of Interest: unknown; Imaging Technique: Axial T1W SE before (a-b) and after (c-d) Gd IV;
     
     
  • Figure 2
    Coronal T1W SE before (a-b) and after (c) Gd IV
     

    Note the high signal areas in the tumour

     
    Area of Interest: unknown; Imaging Technique: Coronal T1W SE before (a-b) and after (c) Gd IV;

    There is high signal material in the outer part of the right maxillary sinus corresponding to retention changes. Note also inflammatory changes in the left maxillary sinus.

     
    Area of Interest: unknown; Imaging Technique: Coronal T1W SE before (a-b) and after (c) Gd IV;

    Contrast enhancement helps to show the extent of the tumour infiltration in the anterior skull base.

    The T2W images help to differentiate tumour limits from retention changes. Tumour has a relatively low signal.

     
    Area of Interest: unknown; Imaging Technique: Coronal T2W FSE;

    The T2W images help to differentiate tumour limits from retention changes. Tumour has a relatively low signal (same as 3a).
